Yes, it's all road salt. The NYS DOT loves it. unfortunatley the person that I bought it from never washed it in the winter. Someone else suggested por 15, but I'm not sure what it is, how it works, where to get it. I assume it treats the rut, but what about the inside of the frame? Por'ed Concrete? :-) anyway. Info and links would be nice. I don't want to get off track, but since you brought it up.....

I know quadratec sells it.
And yeah, its a black base coat that will treat and prevent rust. They also have similar products to help protect from it.
